FW: Makeopts DEBUG=-g kernel option

[Dirk Kotze]

Hi there

I'm experiencing the following problem: All is well when I boot the standard FreeBSD 8.2 GENERIC kernel.  The moment however when I comment out the line the line below, the kernel hangs upon boot after detecting the em0 device (the motherboard has 2 Intel 8257x dual Gigabit Ethernet cards).
makeopts   DEBUG=-g

I'm using FreeBSD 8.2 on a WADE-8020 motherboard with an Intel QM57 chipset and Intel Core i5 CPU.  

The reason I'm trying to remove debugging options from the kernel is that I am trying to make the kernel footprint smaller.

This leaves me with a few questions:
1) What are the risks/drawbacks/advantages of leaving debugging symbols in the kernel?
2) Why would debug symbols (of all things!) make the difference between a working and non-working kernel?
3) Does this point in the direction of some other (more serious problem perhaps?) with the hardware and/or other kernel drivers?

Thanks so much for any assistance.
